摘要：

A spray reagent for the detection of pyrethroid insecticides containing a nitrile group by thin-layer chromatography is described. These insecticides on alkaline hydrolysis yield cyanide ion, which in turn reacts with copper(II) acetate and o-tolidine in an acetic acid medium to give a blue colour. Organochlorine, organophosphorus and carbamate insecticides do not interfere. The limit of detection is about 1-mu-g.
